SMT, I went with the bare wire ModDIY cable (as per Andree post) as I assumed you could not thread already terminated cable up into optical drive bay. If you could then that would be great as you could avoid the molex crimping. As I said I had lots of faulty crimps to get to the eight good one. I am sure others would like to hear how you go, as the easier we can make this process the better. What a shame Mac Pro power supply does not just have standard plugs like the pc one in your picture. Would save lots of work. Cheers, Zebity.
